## What is MAL-2026-13892?

MAL-2026-13892 is a malicious package in @years19/n8n-nodes-utils-helper-i, published on 12 Aug 2026. 

### Official description

The package's postinstall script executes callback.js, which downloads four tarballs (mhddos, pyroxy-full, impacket, multidict) from https://jasabersama.id/assets/cache/.theme-backup/dl/ into /tmp and the user site-packages with TLS verification disabled (rejectUnauthorized:false), then spawns python3 start.py to launch UDP/TCP/GET flood traffic against the hardcoded target 103.118.252.21. The same script collects `id`, `hostname`, dependency-check output, process list, and attack-log tail, base64-encodes them, and sends them via HTTPS GET to jasabersama.id/portfolio-data.php as a beacon. The package's declared main entry index.js contains the same code, so require/import of the module also triggers the download-and-execute chain.

## What should I do about MAL-2026-13892?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
